La Galleria delle Applicazioni raccoglie un'ampia varietà di tutorial e di app dimostrative realizzati con COMSOL Multiphysics in diversi ambiti applicativi, inclusi quelli elettrico, meccanico, fluidico e chimico. E' possibile scaricare i file dei modelli e delle app demo pronti all'uso e le istruzioni step-by-step per costruirli, e utilizzarli come punto di partenza per le proprie simulazioni.
Lo strumento di Ricerca Rapida permette di trovare i modelli che si riferiscono alla propria area di interesse.
Si noti che molti degli esempi qui presentati sono accessibili anche tramite le Librerie delle Applicazioni incorporate nel software COMSOL Multiphysics® e disponibili dal menu File.
A tweeter is a high frequency driver used in loudspeaker systems. An ideal tweeter will produce a constant sound pressure level at a given distance in front of the driver independently of frequency, that is, a flat response. Ideally the tweeter will also, to a certain degree, maintain ... Per saperne di più
In this model, a full transient analysis of a loudspeaker driver is performed, which allow the modeling of nonlinear effects. It extends the linear frequency domain analysis done in the Loudspeaker Driver tutorial model. The analysis accounts for nonlinear behavior of the soft iron in ... Per saperne di più
This example shows how to perform a High Cycle Fatigue (HCF) analysis with a non-proportional load history caused by a transversal force and a torque which are applied in different combinations. Three different fatigue models (Findley, Matake, and Dang Van) are compared. Per saperne di più
This example models a solid oxide electrolyzer cell wherein water vapor is reduced to form hydrogen gas on the cathode, and oxygen gas is evolved on the anode. The current distribution in the cell is coupled to the cathode mass transfer of hydrogen and water and momentum transport. Two ... Per saperne di più
This tutorial shows how to model the propagation of acoustic waves in large pipe systems by coupling the Pipe Acoustics interface to the Pressure Acoustics interface. The tutorial is set up in both the time domain and the frequency domain. 1D pipe acoustics is used to model the ... Per saperne di più
Lattice materials enable the creation of advanced additive manufacturing materials with customized mechanical properties. At the macroscopic level, these heterogeneous materials can be modeled as homogeneous materials. Homogenization techniques can accurately determine the material's ... Per saperne di più
The model studied is a benchmark for a hinged cylindrical panel subjected to a point load at its center. A linear buckling analysis predicts the critical buckling load. Such an analysis will however not give any information about what happens at loads higher than the critical load. ... Per saperne di più
This tutorial demonstrates the operation of a gyroscope based on design provided by Dr. James Ransley at Veryst Engineering, LLC. The model uses the Electromechanics coupling with the mixed finite element formulation in the Electrostatics interface. Per saperne di più
In a polymer electrolyte membrane electrolyzer cell (PEMEC), the two electrode compartments are separated by a polymer membrane. Liquid water is fed to the anode side, forming oxygen gas on the anode, and hydrogen gas on the cathode side, respectively. The respective designs of the ... Per saperne di più
This example demonstrates how to optimize the thickness of a microelectromechanical systems (MEMS) mirror coating material for maximum reflectivity. To reduce the simulation time, a Layered Impedance Boundary Condition is used to model the thin coating material on top of the metallic ... Per saperne di più
